1. Word Meaning and Structure
Arabic ʿurjūn (عُرْجُون) names the woody main stalk or base of a date cluster: the part from which the smaller fruit-bearing branches emerge and which connects the cluster to the palm. With age and drying, this stalk can become slender and curved, forming an arc.
The Qur’an uses ʿurjūn only once, in a comparison with the Moon’s appearance. Understanding the date cluster’s structure matters: ʿurjūn names neither a palm leaf nor the date fruit itself.
Kitāb al-ʿAyn, among the earliest comprehensive Arabic dictionaries, gives al-ʿurjūnu: aṣlu al-ʿidhqi (العُرْجُونُ: أَصْلُ العِذْقِ): the base of the date cluster. It then describes it as yellow and broad and relates its form to the crescent.
Al-Jawharī gives a more detailed definition in Al-Ṣiḥāḥ: al-ʿurjūnu: aṣlu al-ʿidhqi alladhī yaʿwajju wa-tuqṭaʿu minhu al-shamārīkhu fa-yabqā ʿalā al-nakhli yābisan (العُرْجُونُ: أَصْلُ العِذْقِ الَّذِي يَعْوَجُّ وَتُقْطَعُ مِنْهُ الشَّمَارِيخُ فَيَبْقَى عَلَى النَّخْلِ يَابِسًا).
That is, the cluster’s base curves; its smaller branches are cut off, leaving the main stalk dry upon the palm.
Al-ʿAyn and Al-Ṣiḥāḥ: the cluster base and remaining dry stalk
The definition establishes several features.
First, ʿurjūn belongs to the date cluster’s structure, rather than naming the whole tree or a leaf.
Second, the main stalk can remain after the dates and their smaller supporting branches have been removed.
Third, drying and age can make its curved, arcing form more conspicuous.
The important feature in the Qur’anic comparison is therefore the old date-cluster stalk’s slender, curved form.
This does not mean every fresh stalk is perfectly straight and bends only after drying. Its natural structure or the fruit’s weight can curve it while it still carries dates. Drying and age can emphasize its slenderness and curvature.
Qur’anic indexing records ʿ R J N as a quadriliteral entry.
Quranic Arabic Corpus: the sole occurrence of ʿ R J N
Lexicographers disagree, however, about whether the n in ʿurjūn is radical or additional. The proposed connection with ʿ R J in this discussion concerns curvature and inʿirāj. It does not establish an ascent meaning for ʿurjūn.
The word’s concrete, attested meaning should therefore remain distinct from theories about its historical formation.
2. ʿUrjūn within the Date Cluster
Distinguishing ʿUrjūn, ʿIdhq, and Shamārīkh
Accurate understanding requires distinguishing the date cluster’s parts.
The date palm produces clusters whose fruits sit on smaller branches extending from a main axis.
Arabic uses ʿidhq and qinw for a date cluster. Shamrūkh names a smaller branch within it, carrying the fruits; its plural is shamārīkh.
ʿUrjūn chiefly identifies the cluster’s main stalk, to which those smaller branches attach.
The boundaries between these names are nevertheless not uniform in every early usage.
Lisān al-ʿArab records ʿurjūn both generally for an ʿidhq and specifically for one that has dried and curved.
Thaʿlab also defines it as ʿūdu al-kibāsah (عُودُ الْكِبَاسَة), the date cluster’s stalk.
Lisān al-ʿArab: the broader ʿidhq use and Thaʿlab’s definition
There are consequently two levels of usage. Broadly, ʿurjūn can refer to the cluster and its structure; more precisely, in the Qur’anic comparison, its main curved stalk is prominent.
This distinction prevents “date cluster” from suggesting that all its fruits and smaller branches participate in the comparison with the Moon.
“Date-palm branch,” though a possible general expression, may instead suggest the palm’s long leaves.
“Curved date-cluster stalk” or “old base of a date cluster” provides a more precise rendering.
How Does the Stalk Curve and Dry?
A woody supporting stalk connects the date cluster to the tree.
During growth, it supports the cluster, with smaller fruit-bearing branches extending from it.
FAO: the main fruit stalk and its spikelets
After ripening and harvest, those smaller branches may be cut or removed while the main stalk remains.
As it loses moisture, the stalk dries and hardens and can retain its curved, arcing form.
Some specimens also turn yellowish or brownish.
Early lexicographers accordingly compare the stalk with the crescent in curvature, slenderness, and sometimes yellowness.
These characteristics do not have identical dimensions and shapes across all palms and environmental conditions.
Palm variety, cluster size, growth stage, and drying conditions can affect its appearance.
The word therefore should not be assigned one exact, unchanging geometrical shape.
The lexical evidence establishes a stalk belonging to the date cluster which, when old and dry, can have a slender, curved form.
Distinguishing the Stalk from a Palm Leaf
Arabic has other terms for palm leaves, including saʿaf.
The leaf and date-cluster stalk belong to the same tree but are distinct parts.
Leaves perform vital functions such as receiving light and producing food, whereas ʿurjūn forms part of the fruit cluster’s supporting structure.
Rendering ʿurjūn as “dried palm leaf” can consequently obscure the comparison’s object.
The comparison concerns the curved stalk belonging to the cluster, rather than the date palm’s featherlike leaves.
Al-Ṣiḥāḥ and Lisān al-ʿArab make the distinction clear through aṣl al-ʿidhq and ʿūd al-kibāsah.
3. Forms and Early Arabic Evidence
ʿUrjūn and ʿArājīn
The basic word is ʿurjūn; its established plural is ʿarājīn.
ʿArājīn can refer to date-cluster stalks.
Some sources also record ʿurhūn and ʿurjud for similar parts of the cluster.
Abū ʿAmr lists these names alongside ihān.
Lisān al-ʿArab: related cluster names
These forms show that early Arabic had multiple names for the palm and its cluster’s parts.
Related names do not, however, establish a single historical root for all of them.
ʿUrjūn and ʿurhūn, for example, resemble one another in form and meaning, but their exact historical relationship requires morphological and phonetic evidence.
ʿArjana and ʿArjanah
Arabic also records the verb ʿarjana.
Al-Jawharī gives ʿarjanahu: ḍarabahu bi-l-ʿurjūni (عَرْجَنَهُ: ضَرَبَهُ بِالْعُرْجُونِ) in Al-Ṣiḥāḥ: he struck him with the date-cluster stalk.
Here the verb is formed from the implement’s name.
ʿArjana al-thawba also means to pattern cloth with representations of date-cluster stalks.
The verbal noun ʿarjanah likewise concerns depicting and patterning their forms.
Al-Ṣiḥāḥ and Al-ʿAyn: striking with a stalk and patterning
These uses matter morphologically: Arabic treats the four letters ʿ R J N as a unit from which a verb can be formed.
The verb ʿarjana does not occur in the Qur’an.
A Witness from Ruʾbah ibn al-ʿAjjāj
An important witness is a fragment of rajaz by Ruʾbah ibn al-ʿAjjāj:
فِي خِدْرِ مَيَّاسِ الدُّمَى مُعَرْجَنِ
fī khidri mayyāsi al-dumā muʿarjani
Explanatory rendering: “In a curtained enclosure ornamented with beautiful figures and date-cluster stalks.”
Muʿarjan here describes a curtained enclosure patterned with depictions of date-cluster stalks.
Ibn Sīdah draws attention to the structure of muʿarjan in analyzing the witness.
If the n were merely additional and the underlying entry were ʿ R J, preserving n in this derivative would require a separate explanation.
Muʿarjan nevertheless shows Arabic preserving that letter in its verb and derived description.
Ibn Jinnī likewise uses this witness in Al-Khaṣāʾiṣ to defend the radical status of n.
Ibn Jinnī’s Al-Khaṣāʾiṣ: the muʿarjan argument
The argument matters morphologically, but does not make every historical connection between ʿurjūn and ʿaraja impossible.
Two families may be historically related while developing distinct morphological structures in the language as recorded.
Ruʾbah was an Islamic-era poet after the revelation of the Qur’an. This is valuable evidence for early Arabic morphology, but not a pre-Qur’anic witness.
The poetic evidence concerns the status of n; it does not establish that ʿurjūn certainly arose from a quadriliteral verb before the Qur’an.
ʿUrjūn as a Fungus Name
Lexicons also record ʿurjūn for a fungus or funguslike growth. Their older term nabt does not by itself establish a modern botanical classification.
Lisān al-ʿArab describes this ʿurjūn as a span or slightly less in size and considered edible while fresh and moist.
An anonymous rajaz witness in the account examined places ʿarājīn beside another fungus name:
لَتَشْبَعَنَّ الْعَامَ إِنْ شَيْءٌ شَبِعْ
مِنَ الْعَرَاجِينِ وَمِنْ فَسْوِ الضَّبُعْ
la-tashbaʿanna al-ʿāma in shayʾun shabiʿ / mina al-ʿarājīni wa-min faswi al-ḍabuʿ
Explanatory rendering: “If anyone is to be filled this year, you will surely be filled with ʿarājīn and fasw al-ḍabuʿ.” Here ʿarājīn refers to a fungus described as edible by the lexicographers, rather than date-cluster stalks. The anonymous quotation does not establish its date of composition.
Lisān al-ʿArab and Tāj al-ʿArūs: the fungus use and anonymous witness
This use belongs in the lexical account, but should not be transferred to the verse in Yā Sīn.
In Yā Sīn 36:39, the accompanying qadīm and the comparison with the Moon clearly favor an old, curved date-cluster stalk.
A shared name for two things does not establish that either was certainly named after the other.
A visual similarity is conceivable, but proving the historical connection requires independent evidence.
4. The Relationship with ʿ R J: Curvature or Ascent?
Arabic triliteral ʿ R J has several uses.
Forms of ʿaraja can concern ascent; ʿaraj in another use concerns lameness or an irregular gait.
Inʿirāj, from ʿ R J, concerns bending and turning. Iʿwijāj also expresses curvature, but belongs to the separate root ʿ W J. The two should remain distinct in derivation.
Lisān al-ʿArab: distinguishing ʿ R J and ʿ W J
Because an old, dry date-cluster stalk curves, some lexicographers connect ʿurjūn with curvature.
The visual relationship is understandable: a stalk bent into an arc belongs to the field of curved forms.
That proximity does not make ascent the basic meaning of ʿurjūn.
Qur’anic ʿ R J concerns ascent in passages such as Al-Ḥijr 15:14 and Al-Maʿārij 70:4.
ʿUrjūn in Yā Sīn 36:39, by contrast, names a part of the date palm.
Sharing three initial letters does not authorize combining these meanings in translation.
Is the N Additional?
There are two principal structural analyses.
One treats ʿ R J N as the entry, with n radical to its formation.
Ibn Sīdah and Ibn Jinnī support that analysis through muʿarjan in Ruʾbah’s verse.
The other allows a connection with triliteral ʿ R J, treating n as additional in the noun’s formation.
It relies on the semantic resemblance involving curvature.
Al-Basīṭ: additional-n and quadriliteral analyses
Morphologically, muʿarjan provides important support for an established quadriliteral structure in Arabic.
Historically, however, later derivatives can preserve letters that were originally additional.
A letter’s radical status in one period’s morphological analysis therefore does not settle the word’s entire origin.
For Qur’anic study, ʿ R J N is best retained as the word’s recorded entry, with a possible relationship to ʿ R J examined separately.
Either way, the Qur’anic meaning follows the noun and its context, rather than requiring proof of one derivational theory.
5. Qur’anic Use in Yā Sīn 36:39
ʿ R J N occurs only once in the Qur’an.
Yā Sīn 36:39
وَالْقَمَرَ قَدَّرْنَاهُ مَنَازِلَ حَتَّىٰ عَادَ كَالْعُرْجُونِ الْقَدِيمِ
wa-al-qamara qaddarnāhu manāzila ḥattā ʿāda ka-al-ʿurjūni al-qadīmi
Forqan’s existing Persian translation, rendered here in English:
“And for the Moon We have measured out stations, until it returns like an old date-palm branch.”
Kal-ʿUrjūni in the Sentence
Kal-ʿurjūni comprises the comparison particle ka-, the definite article al-, and the noun ʿurjūn.
Al-ʿurjūni is genitive after ka-.
Al-qadīmi is likewise a genitive adjective modifying ʿurjūn.
The comparison consequently selects an old, aged stalk, rather than a stalk in every possible condition.
That qualification is essential to the image.
A fresh stalk may still support smaller branches and dates, whereas an old one can become dry and curved after harvest and the passage of time.
The comparison thus draws attention to its remaining curved form.
The particle ka- should also remain visible in translation: this is resemblance, rather than identity between Moon and stalk.
The Role of Al-Qadīm
Qadīm belongs to Q D M and here describes something that has aged beyond its initial freshness.
For the stalk, age relates to drying, altered condition, and a conspicuous curved shape.
Some lexicographers and exegetes mention a year or another specified period for the old stalk.
Qadīm itself nevertheless specifies no number of days, months, or years here.
Something can be old relative to its fresh condition without one universal time threshold.
“Old” or “aged” is therefore suitable, whereas “one-year-old” or “several years old” does not follow from the Qur’anic wording without independent evidence.
Al-Basīṭ: reported age and time qualifications in commentary
Age need not mean complete decay or breakage. The stalk can be dry and curved while retaining its recognizable form.
Resemblance between the Crescent and the Old Stalk
Lexical sources identify several features in the comparison.
First, slenderness: when only a narrow portion of the Moon’s illuminated surface is visible, it forms a delicate crescent. After drying and the removal of smaller branches, the old stalk can likewise appear slender and reduced in bulk.
Second, curvature: the crescent forms an arc, as does a curved date-cluster stalk.
Third, color: some lexicographers, including Al-Azharī, mention the stalk’s yellowness in this comparison.
In observation, the crescent’s apparent color can also vary with viewing conditions, altitude, and the atmosphere.
This third feature is less constant than the first two. The Moon does not always appear yellow, and old stalks can also vary in color.
The lexical and contextual evidence accordingly makes slenderness and curvature the clearest shared features.
Al-Ṭabarī: the old curved stalk and the late crescent
For someone familiar with palms and date clusters, the comparison provides a concrete, visible image.
Rather than merely stating that the Moon appears slender and curved, it brings a form from agricultural life before the reader.
Ḥattā ʿĀda and the Moon’s Changing Appearance
The verse first states that stations have been measured out for the Moon.
It then gives ḥattā ʿāda, comparing the Moon’s condition with the old date-cluster stalk.
ʿĀda belongs to ʿ W D and concerns returning to a condition.
Here, after passing through different visible conditions, the Moon again reaches a slender, crescentlike appearance.
Across a lunar month, the shape of the illuminated portion visible from Earth changes.
The Moon progresses from a narrow crescent to fuller appearances; after the full Moon, the visible illuminated portion diminishes until a slender crescent appears again.
NASA: changes in the Moon’s visible illuminated portion
The old-stalk comparison suits that slender crescent, especially toward the end of the visible cycle.
ʿĀda does not mean the Moon’s body turns into a date-cluster stalk.
The verse compares appearances; it does not change the Moon’s substance into part of a tree.
Nor does the simile itself yield an exact number of lunar nights, crescent angle, or duration above the horizon.
Those questions require observation and separate investigation.
Does the Old Stalk Mean the Crescent at the Month’s Beginning?
Both the early and late crescents can appear slender and curved.
Their illuminated orientation and location in the observable sky nevertheless differ.
In Yā Sīn 36:39, ḥattā ʿāda follows the reference to the Moon’s stations. That sequence particularly suits the slender appearance reached after passing through them.
The comparison can therefore concern the narrow crescent toward the visible cycle’s end.
The noun ʿurjūn itself is not restricted to the month’s beginning or end. It names the curved date-cluster stalk; the sentence determines the comparison’s temporal setting.
ʿUrjūn alone should consequently not be defined as “the crescent at the end of the month.”
That expression concerns its referent and role in this verse, rather than its independent lexical meaning.
The Surrounding Order of Night and Day
Yā Sīn 36:39 stands among verses describing night, Sun, Moon, and the order of their movements.
Yā Sīn 36:37 concerns night and the emergence of darkness. Yā Sīn 36:38 describes the Sun’s course and its determination.
Yā Sīn 36:39 concerns the Moon’s stations; Yā Sīn 36:40 describes the ordered relationship of Sun and Moon, night and day.
The stalk comparison therefore belongs to a wider description of celestial order.
Within that setting, the Moon’s changing visible appearance signifies an order people can observe.
ʿUrjūn itself nevertheless names neither an orbit, an astronomical station, nor a physical stage of lunar motion.
It is the natural object used in the comparison.
It does not yield a specific scientific conclusion about the Moon’s distance, orbital shape, or the precise mechanism of celestial motion.
This part of the verse explains the observed changing appearance through a familiar natural image.
7. Conclusion and Translation Proposals
Arabic ʿurjūn names the date cluster’s stalk or base, from which smaller fruit-bearing branches emerge.
Some lexical uses extend the name to the cluster generally, but the more precise definition emphasizes its main supporting stalk.
With time, and after fruits and smaller branches have been removed, it can become dry, slender, and curved.
Its plural is ʿarājīn. Arabic also forms verbs such as ʿarjana for striking with a stalk or depicting its shape on cloth.
The n’s status as radical or additional remains disputed in accounts of the word’s historical formation.
Ibn Sīdah and Ibn Jinnī favor a quadriliteral structure through muʿarjan in Ruʾbah’s verse. Sources also discuss a semantic connection with curvature in ʿ R J.
The disagreement does not decisively affect the word’s clear Qur’anic meaning.
The family occurs only once in the Qur’an, as kal-ʿurjūni in Yā Sīn 36:39.
There the Moon, after passing through its stations, is compared to the old stalk.
Slenderness and curvature are the main shared features. Some lexical accounts also mention yellowness, which should not become a fixed, necessary condition of the comparison.
Brief root meaning: The main stalk or base of a date cluster, to which fruit-bearing branches attach; when old and dry, it can become slender and curved.
Meaning of Qur’anic kal-ʿurjūni (كَالْعُرْجُونِ): Like the curved stalk or base of a date cluster, comparing the Moon’s slender appearance.
Proposed word rendering: “Like the curved base of a date cluster.”
The complete kal-ʿurjūni al-qadīmi can be rendered “like the old, curved stalk of a date cluster.”
Forqan’s Persian wording, “like an old date-palm branch,” conveys the comparison generally. A detailed lexical study can sharpen the image by specifying the cluster’s stalk rather than a palm leaf.
The central conclusion is that Qur’anic ʿurjūn names a real date-palm part whose old, curved form resembles the Moon’s slender crescent.
The comparison uses a tangible, familiar object from agricultural life to convey the Moon’s visible appearance.
ʿUrjūn here does not mean the Moon’s orbit, an astronomical station, ascent, or celestial motion. Such concepts belong with other terms in the verse.
It is the date-cluster stalk; its slenderness and curvature make it suitable for depicting the Moon’s crescentlike condition.
